SSD flash drive: what is the difference between SSD and disk, pros and cons and top 5 models

Disk space in your computer or laptop is usually not enough. To safely store data or move frequently used files, you need a device with portable memory. That’s why users decide to purchase an SSD flash drive or external drive. But this choice has its own nuances, because such devices have different sizes and specifications.

What is the difference between SSD drive and flash drive

And the external SSD drive and flash drive – this is a portable storage device. Because of their compactness and mobility, these drives are in demand among PC and laptop users. But there are a number of differences between them.

SSD

SSD USB flash drives have a smaller capacity, but also smaller size. Therefore, moving them is not a problem. Flash drive attached to the keys or placed in a purse or pocket, which allows you to access data in any situation.

The flash drive is used for file transfer, so this device is better suited for situations where you need to access your files on a regular basis. For example, viewing work presentations on computers, playing music from your car radio, or printing documents.

Can this device be quality storage? Yes, because SSD flash drives with the same capacity as SSDs (64GB and 128GB) have already been created. They will also be good for watching high-definition video, storing photos or copies of the OS, drivers for a particular model of hardware, or utilities. To ensure fast data transfer speeds, it is worth choosing a model with a USB 3.0 connector.

An external SSD drive is a device designed to store files (such as backups) and operating systems. The market offers models with both standard capacity (for example, 500 GB) and copies with a capacity of more than 1 TB. Some external SSD drives contain proprietary software that makes them easy to use.

SSD drive

External drives are less convenient than flash drives and cost a bit more. Magnetic models are more prone to mechanical damage due to the presence of moving parts. 2.5-inch instances are powered by USB, so they are easier to carry, but 3.5-inch instances require an additional power source, they are heavier and less compact, so they are used for stationary network data storage.

Advantages and disadvantages of SSD drives in thumb drive format

Advantages:

  1. Unlike standard flash drives, SSDs achieve high data reading speeds.
  2. SSD drives also achieve much higher data transfer rates due to their design. Today’s SSD models can transfer between 50 and 900 MB/s. of data per second. They are limited only by standards and compatibility.
  3. Because of these characteristics SSD flash drives are recognized among laptop users, where they value speed and mobility.

Disadvantages:

  1. SSD drives have two drawbacks that discourage average users. The biggest disadvantage of SSD drives is the price, which, however, is steadily decreasing with the introduction of new production technologies and competitiveness in the market.
  2. The second critical disadvantage of SSD media is the wear and tear of memory modules in terms of writing. Unfortunately, flash chips have limitations on the number of write sessions. The technological limitation of write cycles has forced manufacturers to use a controller that controls the write process so that memory cells are equally consumed. This controller is closely tied to the cache, which has internal software installed that is responsible for logical memory cell addressing, read and write operations.

Thus, when buying an SSD flash drive, the user gets reliability, performance and mobility. However, this does not mean that the SSD does not break, and data recovery from it is much more difficult than from traditional memory.

An overview of the best solutions in terms of speed to capacity ratio

Below is a list of the most prominent models on the market, their features, advantages and disadvantages.

Corsair Voyager GTX 3.0 256GB

The Corsair range includes the Voyager GTX series of portable flash drives, which offer very high performance comparable to SSDs.

Voyager GTX

Pros:

  1. The Flash Voyager GTX models feature a USB 3.0 interface (compatible withUSB2.0) and capacities of 128GB and 256GB. The manufacturer claims to have SSD components in the compact enclosure, which has resulted in improved performance — sequential writes of up to 360 MB/s and reads of up to 450 MB/s.
  2. The memories work with Windows, MacOSX and Linux and require no additional software to operate. They are also compatible with USB Attached SCSI, S.M.A.R.T. and TRIM technologies, which monitor performance and reliable data transfer.

Cons:

  1. The minus include the high cost of this flash drive, for such a price you can buy an external SSD for 500 GB with faster speeds.

STmagic SPT31 USB 3.1 TB

In recent years, NAND technology has experienced rapid development, which has dramatically reduced the price of SSDs. In this case, not only the cost, but also the size is reduced. These conditions give manufacturers like STmagic the opportunity to develop devices like the SPT31.

STmagic SPT31 USB 3.1 TB

Pros:

  1. The STmagic SPT31 comes in five variants, with different capacities – 128GB, 256GB, 360GB, 512GB and 1TB.
  2. The flash drive uses USB1 technology, which gives it read speeds of 500 and 420 MB/s. It is much faster than typical external hard drives, which have an average speed of about 150-180 MB/s.
  3. The main feature of such equipment is that it is quite usabile – the flash drive is used to store games for console or PC, as an external drive for photos and videos, and more importantly – to store important files, such as Adobe Premiere and Photoshop. The manufacturers guarantee that their USB drive is suitable for Windows On-the-Go.

Cons:

  1. Just like the previous option, this flash drive is overpriced.

Orico SSD GV100 USB 3.1 512 GB

The flash drive from ORICO supports multiple ports, it is convenient, fast and suitable for everyday use.

Orico SSD GV100 USB 3.1 512GB

Pros:

  1. The GV 100 has an internal M.2 2242 NVMe SSD and can deliver read speeds up to 940 MB/s over the USB3.1 Gen2 Type-C output interface. This makes it one of the fastest portable solid-state drives on the market. Available in 128 GB, 256 GB, 512 GB and 1TB models.
  2. The size of the Orico portable NVMe SSD is 96mm x 30mm x 9.9mm, a rather small NVMe SSD due to the fact that Orico uses an M.2 2242 SSD inside which is -42mm long.
  3. The blue aluminum alloy case looks solid, and the ABS plastic end cap with a hole allows you to attach the device to keys, for example.
  4. The tiny 512 GB M.2 2242e PCIe NVMe SSD is a dual-sided module running on a Silicon Motion SM2263XT controller and 64-layer TLC NAND flash memory. It’s a DRAM-free SSD that uses the host memory buffer (HMB) in Windows 10 to achieve peak performance.

Cons:

  1. The Orico GV100 NVMe portable SSD is impressive by description, but has some stability issues due to its use of the JMS583 bridge controller.
  2. This flash drive does not connect to your computer without a special cable. There are two of them in the kit: for USB 3.0 and USB Type-C, so you have to carry them with the flash drive at all times.

Teclast 128 GB USB 3.0

The drive from Teclast does not show any impressive results, but this flash drive is quite suitable for normal everyday tasks.

Teclast 128GB USB 3.0

Pros:

  1. The reading speed of the Teclast USB flash drive is 80 MB/s. That’s certainly not as impressive as the flash drives listed above, but this speed is still good for transferring HD video, photos, and other files in a short amount of time, using USB 3.0 technology.

Cons:

  1. Due to its small storage capacity and low transfer rate for an SSD, this flash drive is not suitable for writing an OS to it, but would be a great option for storing large amounts of files.

BlitzWolf BW-UPC2 USB 3.0/Type-C 128GB

The flash drive from BlitzWolf is reversible, the body is made of zinc alloy. This option is for storing files, but not for running the OS from it.

BlitzWolf

Pros:

  1. What makes the BlitzWolf BW-UPC2 special is that the flash drive has 2 standard USB and USB Type-C ports. Thus, the device works with Apple laptops and PCs, with standard USB ports without adapters.
  2. The stick is equipped with USB0 – this provides high speed for writing files. According to the factory specifications, the device is capable of reading data at 150 MB/s and writing at 50 MB/s.
  3. The 128GB size is enough for a system drive, plus there will be room left over for other files. The manufacturer also has a 512GB size – enough for most needs.

Cons:

  1. The flash drive has a speed problem when copying large numbers of small files.
